If the phase difference between voltage ...

If the phase difference between voltage and current is `pi//6` and the resistance in the circuit is `sqrt(300) Omega`, then the impedance of the circuit will be

A

`40 Omega`

B

`20 Omega`

C

`50 Omega`

D

`13 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
`cos phi = (R )/(|Z|)` or `(sqrt(3))/(2) = (sqrt(300))/(|Z|)` or `Z = 20 Omega`
